# Branch｜分支会话
在同一段对话上打开第二条思路。分支出现之前，让观众明确它继承了什么；分支出现之后，再展示不同的继续方式。

## 先完整看到原会话
原会话中保留任务、已完成成果和分支入口。文字使用清晰无衬线，浅色底与低对比消息块保持阅读秩序，强调色只落在新分支或新回复。
## 分叉时保留共同部分
点击分支后，将原会话留在一侧，新会话在另一侧展开。共同上下文的文本与顺序保持一致，新请求和新结果再逐步出现。
两栏宽度可以重分配，但不要同时重排两边全部内容。用一条短连接或共同标题交代来源，随后让新分支成为阅读中心。
## 替换两种真正不同的方向
例如同一品牌视频改为横版与方版，同一方案改为两个风格方向。共享部分不变，新增请求与成果分别对应各分支；不要只把两个窗口的标题换掉。
## 配色与字形
无衬线界面文字与清晰大小层级。
#f7f8f6 · #222522 · #538cbe · #b6cbb9 · #ffffff
## 元素与制作规则
原会话 / 分支节点 / 副本会话 / 继续输入
- 先显示可分支的历史位置，再复制共享上下文
- 两份会话并排短暂比较，选中一份后推近继续
- 标题重复呼应内容分叉，不用无关装饰
## 内容替换
- 可换为设计方案分支，保留共同起点与后续差异
- 替换分支内容，明确哪份是原始与新分支
## 制作参数
[视觉与对象](style.json) · [段落时序](timeline.json) · [位置数据](tracks.json) · [文件清单](manifest.json)
此规范根据参考视频整理。HTML 为可编辑的编排示例；具体数据的来源、精度与有效区间随文件标注。
